CORD WINDER DEVICE
A device for winding, storing, tangle prevention, and protecting cords and/or cables is described. The device for winding a cord includes a frame having a cord access aperture for receiving the cord. The frame also includes an inner spool and a concentrically located spring, such as a flat coil spring, operatively connected to a catch mechanism for engaging the cord. The spring is adapted for winding the cord around the inner spool upon engaging the cord with the catch mechanism and releasing a spring control, such as a ratchet and pawl, that serves to secure tension in the spring. Methods associated with such a device are also described herein.
The present application claims the benefit of U.S. Provisional Patent Application No. 61/305,267 filed on Feb. 17, 2010 and U.S. Provisional Patent Application No. 61/419,105 filed on Dec. 2, 2010, the contents of which are incorporated herein by reference in their entirety.
FIELDThe present invention is related to a device for easily and unobtrusively winding, storing, and protecting cords and/or cables.
BACKGROUNDMany devices have a cord or cable associated with the device. For example, kitchen appliances such as toasters, coffee makers, and blenders all have a power cable for the transmission of electrical power. In the digital age, most audio-visual devices have a cord or cable. For example, users use headphones or earbuds with their MP3 players and smart phones. Moreover, the cost to replace damaged or broken cords/cables/headphones is increasingly expensive. Although there are a variety of winders available to organize and store cords and cables, these conventional devices fail to be user friendly and/or fail to adequately wind and store the cord or cable. As such, cable management, including organizing, storing, preventing tangling, and protecting cords/cables, remains a continued source of frustration for many people. Accordingly, there is a need for devices that organize and/or make cords easier to use and store.
SUMMARYIt is to be understood that the present invention includes a variety of different versions or embodiments, and this Summary is not meant to be limiting or all-inclusive. This Summary provides some general descriptions of some of the embodiments, but may also include some more specific descriptions of other embodiments.
In accordance with one or more embodiments, winders of various size and characteristics are provided to wind and store a variety of cords or cables and to operate “automatically.” As used herein, “automatically” means the winder device in its ready state can operate without turning a crank or handle in order to rotate a winding spool. In use, a folded portion of a cable or cord is engaged around a grasping member, such as a hook. Thereafter, the cord/cable is pulled slightly to disengage a pawl from a spool, and a button is then pushed releasing a spring for winding the cord/cable around the spool. When the two ends of the cord/cable reach the entry point, the refraction stops. To extract the cord/cable, the user pulls the two portions of the cord/cable, either to a desired length or all the way until the cord/cable releases from the winder. Alternatively, a locking hook may be used to lock the cable to the hook so that the cable remains attached to the winder when fully unwound. As the cord/cable is extracted, the spring is re-loaded for the next use. Accidental spin-out is prevented by locking the winder device in its loaded state. Accordingly, a winder device substantially as herein shown and described is provided.

The teeth 344 generally project radially inward (i.e., toward the center of the spool 120) and are sized and shaped to engage at least a portion of the pawl 128. The teeth 344 are oriented at an angle α in order to reduce and/or prevent winder spin-out. Accidental spin-out is undesirable because a user has to then manually re-load the drive spring 124 before the cord/cable may be wound. As such, the engagement between the spool 120 and the pawl 128 is configured such that the drive spring 124 is maintained in a loaded condition until the user is ready to wind the cord/cable (thereby unloading the drive spring). In order to achieve the desirable spool/pawl engagement, the teeth 344 are properly angled to engage and maintain the engagement (i.e., minimize slip) with the pawl teeth 616. In at least one embodiment, this engagement is achieved by orienting the teeth 344 at an angle α that ranges from about 25 degrees to about 45 degrees. In a preferred embodiment, the teeth 344 are oriented at an angle α of about 37 degrees.

It is desirable to be able to keep the drive spring in a loaded state so that the spool is ready to wind the cable/cord when the user is ready. As such, it is desirable to prevent accidental spin-out (or unloading) of the drive spring. In at least one embodiment, accidental spin-out is prevented by preventing the button from moving when a cord/cable is not engaged with the winder device. That is, the button cannot move from a first position of use to a second position of use unless and until a cord is engaged with the spool and the user pulls slightly on the cord while moving the button. A user who completely removes his or her headphones from the winder device is prevented from accidentally unloading the drive spring because he or she may not move the button to a second position of use until the cord/cable has been re-engaged with the spool's grasping members and the user has pulled slightly on the cord/cable. Similarly, a user who partially removes his or her earbuds from the winder device is prevented from accidentally unloading the drive spring because he or she has to pull slightly on the cord/cable before he or she may move the button to a second position of use. Preventing accidental spin-out is highly desirable for the user who, for example, takes his or her earphones out of the winder device and then places the winder device in a backpack, briefcase, or purse while he or she is using the earphones. In this example, the winder device will not accidentally unload while in the backpack, briefcase, or purse and the winder device is ready to wind the cord/cable when the user is ready to. If, however, the drive spring does spin-out or unload accidentally, the user may simply reload the drive spring by manually rotating the spool.
